External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
External ballistics is the part of the science of ballistics that deals with the behaviour of a non-powered projectile in flight. External ballistics is frequently associated with firearms , and deals with the unpowered free-flight phase of the bullet after it exits the gun barrel and before it hits the target, so it lies between transitional ...
The projectile's motion in flight is known as its external ballistics, and its behavior upon impacting an object is known as its terminal ballistics. A bullet can be made of virtually anything (see below ), but lead is the traditional material of choice because of its high density, malleability , ductility , and low cost of production .
Often broken down into internal ballistics, transitional ballistics, external ballistics and terminal ballistics. Battle rifle: A service rifle capable of semi-automatic or fully automatic fire of a full-power rifle cartridge. Bayonet lug: An attachment point at the muzzle end of a long gun for a bayonet.
Ballistics (gr. ba'llein, "throw") is the science that deals with the motion, behavior, and effects of projectiles, especially bullets, aerial bombs, rockets, or the like; the science or art of designing and hurling projectiles so as to achieve a desired performance.
Transitional ballistics, also known as intermediate ballistics, [1] is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized, so it lies between internal ballistics and external ballistics.
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
A linear hammer is similar to but differs from a striker in that the hammer is a separate component from the firing pin. [10] When released, a linear hammer, under spring pressure, slides along the bore axis rather than pivoting around a pin placed perpendicular to the bore, as with the more common rotating hammer.
